Eureka Mignon Libra Weight-Based Espresso Grinder Overview
This refurbished Eureka Mignon Libra is an Italian-made home espresso grinder that doses by weight rather than by time. Its Intelligent Weighing System lets you program doses in 1/10th of a gram, with a variation of only 0.2g from one grind cycle to the next. The body is powder coated aluminum, and an adjustable portafilter fork holds the basket while it grinds.
The Libra keeps the touch screen of other Mignon models, so single and double doses are switched freely, and the weight is changed in tenths of a gram with the plus and minus buttons. A manual mode remains available for freehand grinding while you are still working out a dose.
Key Features
- Weight-based dosing programmable in 1/10th of a gram, accurate to 0.2g per cycle
- Anti-vibration weighing design that keeps grinding even if the grinder is bumped
- Motor stops at once if the portafilter is removed, so grounds do not spill across the counter
- 55 mm flat hardened steel burrs with a 1350 RPM motor producing 1.4 – 1.8g/s for espresso
- ACE system that removes static from the grounds to limit clumping and support dose consistency
- Patented micrometric stepless adjustment with an extra comfort knob, running at about 73 dBA
- Portafilter fork and cradle adjust with a hand screw at the base to suit portafilters from any manufacturer
Who It’s For
This grinder fits home baristas who want repeatable doses from a compact machine and prefer to set a target weight instead of timing a shot. Anyone looking for an Italian weight-based option in the Mignon family will find it here.
